So this bank did the final part of their underwriting 2.5 months into the process while my 2nd lender (the one that I finally went with) was able to give me the green-light after only 2 weeks...

I agree with @Jonathan Greene that the question is vague, so my advice will have to be as well.The short answer: MTRs are real estate, so just like all real estate, any place that can long-term-rent cash flow with increasing jobs/population can be a suitable site to purchase. 

@Jonathan Greene you didn't, that comment was more in reference to other responses on the thread.

Quote from @Jaycee Greene: As long as you feel you can cover large capex, there's not much need to keep much cash in the account, though I would keep the SD in there, so it looks like you're not co-mingling funds.

What are some rental property green flags you've seen that scream buy? 

I would recommend the One Brokerage, David Greene team.

Or find a property that is under-utilized or has below market rents.Otherwise, you could also do the OPPOSITE of the great advice from @Jonathan Greene and buy a property with multi-bed units or live in the larger unit and rent out the smaller unit - while getting a roommate(s).

Quote from @Jaycee Greene: @Shaylynn O'Leary well, that's at least someone with "eyes and ears" in the actual market. 

I'm currently reading David Greene's book on BRRRR and was curious about how you all go about planning or visualizing added rooms to potential purchases.
